I have this ottoman coin that is a silver coin but covered with gold because was used as a pendant . I haven't find any info in the net so the best place for it i think is this forum. it is 20 para ah 1255 year 4 and below i would post the photos . any help would be sincerly appreciated .
ok found it in my 19th century Krause world coin catalog Egypt 1255/4 (1842) KM#227 , weight 0.6800 g. .833 silver , 16mm size grade/value VG-$13.50 F-$27.50 VF-$50.00 XF-$75.00 UNC-$150.00 not sure what your coins grade is ? not sure how much value will be taken away because it was gold plated ? the hole in it will also bring the value down. some people do collect holed coins. Krause values may differ than real market value prices.
